SCAFFOLD BRACKET

SUPPORT D'ECHAFAUDAGE

English Abstract

ABSTRACT OF THE DISCLOSURE

A scaffold bracket for mounting on a
ladder. The bracket comprises at least two legs,
which are connected at one end to define a junction,
said legs divergingly extending from the junction to
their free ends. A plurality of first rung engaging
members are distributed along the legs from their
free ends and terminate short of the junction. A
link is attached at the junction and terminates in a
second rung engaging member. The bracket is so
constructed and arranged that the legs are placed
over a selected rung of the ladder and are engaged
thereon by engagement of a first rung engaging
member, the second rung engaging member is engaged
over an upper located rung, a second bracket is
similarly mounted on a second ladder placed side by
side relative to the first ladder, and a wood plank
is placed on the two brackets to constitute a scaf-
fold.

Description

Thi.s i.nventi.on relates to a scaffold
bracket. More parti.cularly, the present invention
relates to a scaffold bracket of the type to be
mounted on a ladder and to be used in pai.rs along
with a wood plank to constitute a scaffold.
The preparation of a scaffold to work on a
residential, commercial or industrial building always
presents a problem. If the scaffold is built from
planks, this is time consuming and is expensive in
terms of materi.aIs which cannot normally be reused
for the same purpose. If, on the other hand, commer~
cially available scaffolding is used, this i.s expen~
sive, and is not always available, not to mention the
fact that the one that could be obtained does not
::~ 15 always fit the intended use.
Complicated designs are known such as those
disclosed in the followi.ng U.S. Patents~
1,228,868
2,418,597
~ 20 4,306,700
i~ .However, because of the complicated mechan-
ical structures of these devices and the fact that
they would be expensive to produce, they are not
readily available on the market and do not constitute
articles that` a handyman would normally acquire for
; occasional use.
It is an object of the present invention to
have access to an easy to install li.ghtweight scaf-
fold by;using two ladders and brackets and a plank of
wood.
. Accordi.ng to the invention there is pro~
~: vided a scaffold bracket for mounting on a ladder,
the bracket comprising at least two legs, the legs
- connecting at one end to define a junction, diver-
.~ 35 gingly extendi.ng from the junction to their free
ends. A plurality of first rung engaging means are

"


distributed along the legs from the free ends and
terminate short of their one ends. Linking means are
attached at the junction and terminate in a second
rung engaging means. The bracket is so constructed
5and arranged that the legs are placed over a selected
rung of the ladder and is engaged thereon by engage-
ment of a first rung engaging means, the second rung
engaging means being engaged over an upper located
rung, a second bracket is similarly mounted on a
10second ladder placed side by side relative to the
first ladder, and a wood plank is placed on the two
brackets to constitute a scaffold.
- According to a preferred embodiment, the
junction consists of an elongated member which
extends from a point where the one ends meet, the
i~ linking means being attached at the free end of the
elongated member.
According to another preferred embodiment,
the linking means consists of a chain link, the
20second rung engaging means consists of a steel hook
provided at the free end of the chain link, enabling
to circle the upper located rung with the chain link
and secure same thereover with the hook.
~- ~ According to another preferred embodiment,
the first rung engaging means may comprise a plural-
ity of downwardly projecting prongs which enable the
~- selected rung to fit between adjacent corresponding
1!~ ' prongs of each leg.
' According to another preferred embodiment,
;30 ~~ there is provided a transverse member connecting the
legs between the junction and the free ends.
The invention will now be illustrated by
means of the annexed drawings, which are only given
for the purpose of illustration and in which~
; 35FIGURE 1 is a perspective view of a scaf-
fol~ bra~ket according to the inventlon and

FIGURE 2 is a sketch of the scaffold
bracket accordi.ng to FIGURE 1 appli.ed to a ladder.
Referring to the drawings, it will be seen
that the scaffold bracket 1 which i.s illustrated
comprises two legs 3 and 5 which are connected at one
end to defi.ne a juncti.on 7. As shown, the legs 3 and
5 extend by divergi.ng from one another to the free
ends 9 and 11 of respecti.ve legs 3 and 5. The
junction 7, as shown, consists of an elongated member
which extends from a point 13 where the divergi.ng
legs meet for a certai.n di.stance as shown i.n the
drawlngs .
The bracket is associated with a chain link
15 having a yoke 17 at one end and a hook 19 at the
opposite end. The chain link 15 is attached at the
~:~ end 21 of the elongated member by means of the yoke17 all in the manner as shown in the drawings.
A plurality of downwardly projecti.ng prongs
;~ 23 and 25 are provided respectively for legs 3 and 5.
The number can vary at will. In the embodiment
~'2'~ illustrated there are seven prongs for each leg, it
~ being understood that this number is not critical.
Y~ In operation, it is merely necessary to
~: place a bracket with the prong section over a rung of
25: the ladder 27, it being understood that the space
between any two adjacent prongs will be selected
depending on ci.rcumstances. The chain link 15 is
i5'~ then drawn to an appropriate upper rung, then the
chain link 1.5 is allowed to circle an upper rung and
;: 30 securing is done through the hook 19. After having
similarly mounted a second bracket on a second ladder
placed side by side relative to the ladder 27, a wood
plank 29 is placed on the two brackets to constitute
a scaffold.
